Which of the following situations of altered perfusion could be triggered by chronic obstructive pulmonary disease?

Ventilation perfusion mismatching

Impaired cardiac output

Impaired circulation

Excessive cardiac demand

Answer and Explanation

The Correct Answer is A

A. In chronic obstructive pulmonary disease (COPD), airflow obstruction leads to ventilation-perfusion (V/Q) mismatching. This means that some parts of the lungs may receive air but not enough blood flow, or vice versa, resulting in inefficient gas exchange and reduced oxygenation. This is a hallmark of COPD.

B. While COPD can eventually affect the heart, particularly leading to right heart failure (cor pulmonale), it does not directly impair cardiac output in the early stages. The primary issue in COPD is with lung function.

C. COPD does not directly impair circulation but can lead to pulmonary hypertension and strain on the circulatory system over time. However, impaired circulation is not the primary issue triggered by COPD.

D. COPD may lead to increased work of breathing, but it does not directly cause excessive cardiac demand in the same way that conditions like anemia or sepsis might.

Correct Answer is A

Explanation

A. Emphysema, a type of chronic obstructive pulmonary disease (COPD), is the most common cause of a barrel chest. It occurs due to the destruction of the alveoli, leading to air trapping and overinflation of the lungs, which causes the chest to take on a rounded, barrel-like appearance.

B. Pneumonia typically causes acute symptoms like fever, cough, and difficulty breathing, but it does not cause the chronic lung changes that result in a barrel chest.

C. Tuberculosis can cause lung damage, but it does not typically result in the barrel chest shape. It is more associated with symptoms like cough, hemoptysis, and weight loss.

D. Acute respiratory distress syndrome (ARDS) is an acute condition involving rapid onset of severe respiratory distress, often due to trauma or infection. It does not cause the chronic structural changes seen in a barrel chest.

A. Anorexia B. Edema of fluid overload C. Vomiting D. Nausea

Correct Answer is B

Explanation

A. Anorexia is a common manifestation of SIADH due to the effects of hyponatremia (low sodium levels) and fluid retention.

B. Edema of fluid overload is not a typical manifestation of SIADH. While SIADH leads to fluid retention due to excess antidiuretic hormone (ADH), the excess fluid is typically intracellular and does not cause peripheral edema as seen in conditions like heart failure or nephrotic syndrome.

C. Vomiting is a common manifestation of SIADH, often related to the effects of hyponatremia, which can irritate the gastrointestinal system.

D. Nausea is also a common symptom of SIADH due to the imbalance of electrolytes, particularly low sodium levels, which can affect the brain and lead to nausea.
